Polishing device special for center lathe

Abstract

The invention relates to a polishing device special for a center lathe. The polishing device comprises a motor, a tool pedestal, a polishing wheel, an abrasive belt and a pre-tensioning wheel and is characterized in that the motor is installed on the tool pedestal of the center lathe, the polishing wheel is installed on an output shaft of the motor, the pre-tensioning wheel for providing tension force for the abrasive belt is installed on a lathe body of the center lathe, the pre-tensioning wheel can rotate around a rotating shaft, the pre-tensioning wheel and the polishing wheel are sleeved with the abrasive belt, the motor drives the polishing wheel, and then the abrasive belt is driven to rotate around the polishing wheel and the pre-tensioning wheel, so that polishing of the surface ofa thin long axial workpiece is achieved. According to the polishing device, based on the premise that a special polishing machine is not added, by means of the machining precision of the lathe, the polishing device is installed on the tool pedestal of the lathe, polishing of the machined thin long axial workpiece is available, and time of workpiece transferring and a working procedure of workpiece transferring are reduced, the labor intensity of a worker is lowered, the polishing speed is high, the polishing efficiency is high, the quality of a polished product is good, the precision is high,and not only is the production efficiency of an enterprise effectively improved, but also the production cost of the enterprise is greatly reduced.

Description

technical field [0001] The invention belongs to the field of mechanical processing, and in particular relates to a special grinding device for ordinary lathes. Background technique [0002] In actual production and processing, a processing problem often arises. For slender shaft workpieces with a length of more than 3 meters and a diameter of less than 150 mm, such parts are very difficult to process when the surface roughness and straightness are required. Due to the limitation of the rigidity of the parts itself, it is difficult to complete the processing with a special grinding machine, and the time-consuming and labor-intensive processing costs are very high, which seriously limits the development of the enterprise. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a special grinding device for ordinary lathes. The process of transferring the workpiece is simplifi...
